The Arbitrator functioned as a Venator-class Star Destroyer within the ranks of the Republic Navy throughout the duration of the Clone Wars.
In approximately 21 BBY, the Arbitrator met its end. It was obliterated during an assault initiated by the Recusant-class light destroyer commanded by General Grievous. However, Clone Commander Cody, along with a Jedi Knight, successfully rescued the remaining crew, preventing their capture by Grievous. This rescue was accomplished with assistance from Jedi Master Obi-Wan Kenobi and Jedi Padawan Ahsoka Tano.
